Abstract: The invention relates to a process for the preparation of a catalytically active mass of the formula… Mo12Bi0.1-10Fe0.8-12(Co,Ni)0.1-10P0-2A0-10B0.001-1OX,… in which A represents the elements arsenic, antimony, zinc, thallium, tungsten, alkaline earth metals, zinc and/or chromium, B represents at least one of the metals sodium, potassium, rubidium, caesium and/or indium and X represents numbers determined by the atomic valencies of the individual elements, in which the iron and molybdenum fraction is introduced wholly or partially in the form of a dried powdered iron molybdate gel to an aqueous solution or suspension of the other components and the mixture, with stirring and possibly heating, is brought to a gel-like solidified state, then comminuted and dried at elevated temperature and finally calcined.

IPC: C07C69/52
Abstract: A PROCESS IS DESCRIBED FOR CONTINUOUSLY PREPARING ALKYL ESTERS OF (METH)ACRYLIC ACID BY REACTING (METH)ACRYLIC ACID AND ALKANOLS HAVING FROM 1 TO 5 CARBON ATOMS IN HOMOGENEOUS, LIQUID, SOLVENT-FREE PHASE AT ELEVATED TEMPERATURE AND IN THE PRESENCE OF AN ACIDIC ESTERIFICATION CATALYST, IN WHICH THE (METH)ACRYLIC ACID, THE ALKANOL AND THE ACIDIC ESTERIFICATION CATALYST ARE FED TO A REACTION ZONE (5, 6), THE WATER FORMED DURING A RESIDENCE TIME IS REMOVED RECTIFICATIVELY AS A CONSTITUENT OF AN ALKANOL-COMPRISING MIXTURE IN A RECTIFICATION UNIT III ATTACHED TO THE REACTION ZONE (5, 6), THE DISTILLATE OBTAINED HERE IS SEPARATED INTO AN ALKANOL-COMPRISING ORGANIC PHASE AND A WATER-COMPRISING AQUEOUS PHASE, THE ORGANIC PHASE IS RECYCLED INTO THE RECTIFICATION UNIT III AND THE AQUEOUS PHASE IS DISCHARGED, AND A REACTION MIXTURE (21) IS DISCHARGED FROM THE REACTION ZONE (5, 6), WHICH COMPRISES -FEEDING THE REACTION MIXTURE (21) DISCHARGED FROM THE REACTION ZONE (5, 6) TO A CATALYST REMOVAL UNIT V AND SEPARATING IT IN THE CATALYST REMOVAL UNIT V INTO A TOP STREAM (56) COMPRISING THE ALKYL ESTER OF (METH)ACRYLIC ACID AND DEPLETED IN ACIDIC ESTERIFICATION CATALYST, AND A BOTTOM STREAM (54) COMPRISING THE PREDOMINANT PORTION OF THE ACIDIC ESTERIFICATION CATALYST AND DEPLETED IN WATER, AND -INTRODUCING THE TOP STREAM (56) COMPRISING THE ALKYL ESTER OF (METH)ACRYLIC ACID INTO A RECTIFICATION UNIT I AND, WITH ADDITION OF WATER, SEPARATING IT INTO A TOP STREAM (23) COMPRISING THE ALKYL ESTER OF (METH)ACRYLIC ACID, AND A BOTTOM STREAM (52).
